All network engineers want to burn down the IPS. That's nothing new. Disruptions should not be common. Most modern IPS/IDS solutions are pretty good about minimizing the downtime. ISS stuff is pretty good about this, although not great.
I'd say your outsourced provider may have some issues or you need to update to the latest versions. Firmware updates should be scheduled to coincide with normal maintenance windows in case there is any downtime. Signature updates can also be scheduled for a reasonable daily or weekly window. Network admins will blame EVERYTHING on the IDS/IPS because it's easier for them to blame the IPS then for them to do their jobs. There is a possibility you have network infrastructure issues. You might want to consider getting a third party assessment of your network. That way you can get an objective analysis that will hold more weight with management. Good luck.

Now and then, the IDS will cause disruptions to the network, especially after updates. We have an IBM (ex ISS) Intrusion Detection System with a few network sensors and several host sensors. The IDS is not managed by us but we have it outsourced. The disruptions mentioned above cause our network engineers extreme dissatisfaction (and anxiety) about the IDS and they would "burn the damn thing", if they could. We have 2 - 3 serious issues, causing downtime, per year. My questions are: - Are any of you experience the same issues? - Is these disruptions common to others or should we seriously consider replacing the IDS and/or the outsourcing company? - Could this be an issue with our network infrastructure? I will appreciate any thoughts. Thanks, ST ----------------------------------------------------------------- Securing Your Online Data Transfer with SSL.
